Topic: RME and US broadcast levels for UFX

Hello,

Many of us in the RME user community have been talking to RME for years about making their product with US broadcast analog levels - -20dBfs=+4dBu.  This alone prevents RME from being used in many television broadcast situations.  Setting up one of the software-switchable analog levels to be -20dBfs=+4dBu is not very hard, in most instances requiring no changes to the power supply rails.  Some other devices even offer an option - the broadcast level option - for an additional cost.  Why is this so hard and why can't RME pay attention to a significant number of users who have complained?  The UFX looks like a great product but once again RME missed this segment.

Sincerely,
Hugh

Re: RME and US broadcast levels for UFX

Hi Hugh

This has already been addressed in this forum see:

http://www.rme-audio.de/forum/viewtopic … 092#p45092

and the following posts.

Note that the UFX specifies one pair of non-servo balanced outputs on XLRs that will hit +24.  Inputs are limited because the peak voltage of +24dBu will exceed the ?15V rail voltage of the input amps.

Out of interest, can you advise which interfaces of American design in the RME USB/FW price range will handle +24dBu in?

No. You just need an input stage that is designed to handle this level as well as the other levels (the ones 99% of the users need). That adds components and costs, and would only adress the inputs, which is then critizied again as half-baken solution. So we skipped it completely.
